I know that some audiophiles don’t like to review measurements but they are instructive.
A DAC with 0.2 dB deviation in frequency response and distortion and noise below 0.01% is commonplace.
A speaker with linear frequency response within +/- 2dB both on and off axis and distortion below 0.5% for most of the audible range is commendable.
It is much more important to focus on improving the component that is orders of magnitude worse than rest of the chain - and that is the speakers (and room).
